Generators
UUID, ULID, NanoID, fake data, mock JSON, QR codes, lorem ipsum, and more.
UUID Generator
UUID generator — create UUID v4 (cryptographically random) or UUID v7 (time-ordered, RFC 9562) identifiers instantly. Bulk-generate up to 100 UUIDs at once and download as a text file. UUID v7 is ideal for database primary keys — it is lexicographically sortable and avoids index fragmentation.
Open →Lorem Ipsum Generator
Lorem ipsum generator — create placeholder text by paragraphs, sentences, or words. Standard lorem ipsum corpus for typesetting mockups, UI wireframes, and design prototypes. Copy instantly with no signup required.
Open →Slug Generator
Generate URL-friendly slugs from any text. Converts titles to lowercase kebab-case, strips diacritics (é→e, ü→u), removes special characters, and handles Unicode. Perfect for blog post URLs, product slugs, and SEO-friendly permalinks.
Open →Mock JSON Generator
Generate realistic mock JSON data from a JSON Schema. Define fields with types, constraints, and format hints (email, uuid, date, url) and get sample data for API testing, UI prototyping, and unit test fixtures. 100% client-side.
Open →ULID Generator
ULID generator — generate Universally Unique Lexicographically Sortable Identifiers. 48-bit timestamp prefix + 80-bit random component, Crockford Base32 encoded. Time-ordered, URL-safe, case-insensitive. Better than UUID v4 as a database primary key.
Open →NanoID Generator
NanoID generator — create secure, compact, URL-safe unique IDs using crypto.getRandomValues. Default 21-character IDs have the same collision probability as UUID v4 but are shorter. Configurable alphabet and length.
Open →Fake Data Generator
Fake data generator — create test data with realistic names, emails, phone numbers, addresses, company names, dates, IPs, and usernames. Bulk-generate CSV or JSON for seeding databases, testing forms, and API development. 100% client-side.
Open →QR Code Generator
QR code generator — create QR codes for URLs, text, contacts, and WiFi credentials entirely in your browser. Output is clean SVG (infinitely scalable). No watermark, no sign-up, unlimited use. Download and use on print materials, presentations, or websites.
Open →.gitignore Generator
.gitignore generator — create a .gitignore file from 20+ built-in templates for languages (Node.js, Python, Java, Go, Rust), editors (VS Code, JetBrains), and operating systems (macOS, Windows, Linux). Combine multiple templates into one clean file.
Open →License Generator
Open source license generator — create a complete LICENSE file for MIT, Apache 2.0, GPL-3.0, BSD, ISC, or MPL-2.0. Enter your name and year, choose your license, and copy or download. Includes all SPDX-standard licenses used on GitHub.
